Oh I know. I dont feel sick, but I get so irritable. I was up til 5 yesterday, woke up at 6. Stayed up til 10, and woke up for the day at 12. Then I finally get to see my boyfriend and Im tired as hell, take a nap from 10 to about 11:30. And now Im here, wide awake at quarter past two. It sucks! Im allllllways up if youre ever too bored.
Usually what I try to do to fall asleep is eat a nice meal,[though it hasnt been doing anything lately] And reading puts a strain on your eyes and it makes you slowly concentrate on that rather than being sleep deprived.

Good luck to youu!
